The JANUS® workstation is a highly precise and reliable liquid handling workstation that can be used across various research and clinical workflows including:

  • Clinical primary sample reformatting and preparation
  • QPCR plate prep
  • NGS library construction
  • Small molecule analysis
  • Proteomics
  • Cell culture

In support of these workflows, the JANUS® workstation is compatible with a wide range of consumables. From disposable tips to microplates and reagent troughs, PerkinElmer provides high quality consumables to meet your liquid handling needs.

Plastic Tips

The types of plastic tips that are used have four distinct properties:

Filter: Filter pipette tips uses a membrane to provide a filter which functions as a barrier between the pipetting head and the liquid it is aspirating and dispensing. These tips use a robust manufacturing process and multiple quality inspections to ensure proper tip quality and filter placement. This ensure no cross-contamination through aerosols between samples, reduces aerosol intake to the workstation and are ideal for qPCR and other sensitive applications.

Sterile: Sterile pipette tips are made from medical grade 100% virgin polypropylene and have been sterilized using irradiation to the current regulatory maximum of 10-6 SAL. This is equivalent to the sterility assurance level (SAL) required by the medical device industry and ensures a product free from the following contaminants: bioburden, human DNA, DNase and RNase. This eliminates any contamination and these tips are primarily used for most cell culture applications.

Conductive: Conductive pipette tips are manufactured with a small amount of graphite along with the polypropylene to enable an electric current in the tips. The graphite is inspected to ensure a proper conductivity of 1-25 kOhms before the tips are manufactured. These conductive tips allow the JANUS® workstation to detect the surface of liquids and pipette from a defined depth relative to the surface of the liquid.

Wide Bore: Wide bore pipette tips have a distinct wide shape at the end of the pipette tip. This enables the JANUS® workstation to aspirate and dispense liquid in a gentler manner and are designed for more viscous materials like the buffy coat of fractionated blood. These tips are polished with precision tools to reduce the sheer resulting in minimal liquid retention and reduces the molecular distortion in sample aspiration. These tips are ideal for working with cellular matrices, genomic DNA and other viscous sample types.

VariSpan™ Tips

The VariSpan™ arm is used to aspirate and dispense liquids from tubes to vials and plates. The tips below are used with this VariSpan™ arm and have a dynamic volume range from 0.5 µL to 5000 µL.

Modular Dispense Technology (MDT) Head Tips

The MDT head is used for precision pipetting 96, 384 or 1536-channels at a time. This is ideal for high-throughput bead-based clean-ups and NGS sample transfers in 96, 384 or 1536 microplates. Each head can be automatically switched within an automated protocol on the JANUS® workstation and enables true walk-away automation.
